I've never seen the point of anything more complicated than addition, subtraction, multiplication, and division. I excelled in algebra and sucked at everything after that except statistics. Really, what's the point of it? I'm never going to use it, and the only thing you can do with a math degree is teach it or write down numbers in a cubicle all day long while contemplating suicide.
Oh yeah, and I can figure out prices, sales tax, and tips much faster than my NT friends. They probably get more pleasure out of it though... or something.
